During the World Cup, the high-frequency sports betting whale Swisstony emerged, with over 139,000 trades and almost $20 million in profit.

BlockBeats News, July 12th. Data from the prediction market platform Predict.fun shows that during the 2026 FIFA World Cup in the United States, Canada, and Mexico, a top sports high-frequency trader named swisstony emerged. Since entering the market in July 2025, this whale has made a total profit of $18.648 million, with a maximum single profit of $1.2 million. He has made a high number of predictions, reaching 139,304 times, and his profit curve has been steadily rising.

His World Cup prediction performance is remarkable. He excels at operating reversely when popular odds are overestimated, relying on high-frequency small-scale edge trading to accumulate huge profits. Although the average profit per transaction is small, his win rate is stable, and the cumulative effect is extremely strong. In June, this whale successfully made a profit of approximately $9.5 million by contrarily predicting popular teams (such as England, Spain, and Belgium), briefly becoming the platform's fifth most profitable user.

swisstony is currently focusing on the France vs. Spain match on July 14th local time, with heavy positions in various submarkets of the game. His main strategy still involves making a large number of "No" predictions, especially on low-probability exact scores, combined with some handicap and over/under bets. The whale swisstony often ranks high on the monthly profit leaderboard in the prediction market, with daily profits exceeding $2 million at times. Analysts believe that this whale may be using automated tools or real-time data assistance.
